A personal observation. Competing in an IPSC match, a big one! Way back, one stage was a real quicky, just 4 shots, 20 points available.
Scenario, your pistol was holstered, my 1913 Colt .45, locked and cocked.
You stood in front of a closed door, in your right hand (My shooting hand) you held a Pizza a 1 foot circle of plywood!
You dropped the "Pizza" opened the door, this triggered two cardboard targets, which were lying down, on their backs, to swing up, and down on their faces.
About two seconds was your exposure time.
I MISSED THE SAFETY CATCH!!!!!!!!!!!!! TARGETS GONE!
Never done that prior to this high pressure panic.
Just like you would experience in a real gun fight! Retired 1911, Glock 17 Hello!
In shooting in NY State Finger Lakes, IPSC, Mike Braun, the Range Master said I could not shoot that pistol, it had no safety catch. "Mike, it is double action only? the trigger COCKS the firing pin" He swallowed that.
1984, introducing the Glock 17 to IPSC. 34 year later, after selling the Glock pistols to the Toronto Police Force! Against my advice, they picked .40 cal.
I now live in the USA, and carry a Glock 19 4th gen, every day!
